Specific embodiment

It is a specific embodiment of the utility model below, the utility model is described further now in conjunction with attached drawing.

In conjunction with shown in Fig. 1 to Fig. 5, a kind of centrifugal hygienic self priming pump is fixed with supporting leg, electric machine assembly under electric machine assembly 16 16 output ends are connected with centrifugal pump 12.Centrifugal pump 12 includes pump case, has pump chamber, the built-in impeller of pump chamber in pump case；In centrifugal pump The water inlet pipe and outlet pipe being connected to pump chamber are installed, water outlet tube end is equipped with titting water outlet 15 on 12 pump cases；Centrifugal pump 12 provide power by electric machine assembly 16, with trandfer fluid.This part is the prior art, does not do tired state.

Water inlet pipe includes the water inlet pipe straight pipe 4 connecting with centrifugal pump 12,4 outer end of water inlet pipe straight pipe be connected with vertically to Elbow 3 under the water inlet pipe of upper 90-degree bent, again to horizontal direction 90-degree bent after 3 upper end of elbow is connected with vertically upward under water inlet pipe Water inlet pipe on elbow 2, elbow 2 connects horizontal water inlet pipe connector 1 on water inlet pipe.Water inlet pipe connector 1 is higher than water inlet pipe straight tube Section 4.On water inlet pipe under elbow 2, water inlet pipe the center line of 4 three parts of elbow 3 and water inlet pipe straight pipe and centrifugal pump 12 rotation Turn center line on the same perpendicular, makes 12 pump chamber of centrifugal pump, circulating reflux pipeline, cavity composed by water inlet pipe in this way Have the function of storing liquid, after ensure that liquid is added for the first time in centrifugal pump 12, water inlet pipe, pump chamber and circulation when next time uses Remain to save the circulating liquid of sufficient amount in return line, to complete self-suction function.

A circulating reflux pipeline is connected between 12 pump chamber bottom of 4 bottom of water inlet pipe straight pipe and centrifugal pump, is recycled back to Flow tube road is specifically:

Return pipe lower contact 11 is connected in 12 pump chamber bottom of centrifugal pump, 11 lower end of return pipe lower contact connects fast under return pipe Speed dismounts hoop component 10, and 10 lower end of fast assembling-disassembling hoop component connects trap 9 under return pipe, and 9 upper end of trap connects Taper Pipe 8 under water pipe are taken back, 8 upper end of Taper Pipe connects fast assembling-disassembling hoop component 6 on return pipe under return pipe, quickly tears open on return pipe Dress 6 upper end of hoop component connects return pipe epicone pipe 5, connection return pipe top connection 14 in 5 upper end of Taper Pipe on return pipe, on return pipe 14 upper end of connector connects water inlet pipe straight pipe 4.The center line of entire circulating reflux pipeline and the center line and centrifugal pump of water inlet pipe 12 rotation centerlines are on the same perpendicular.And trap is located at extreme lower position, can effectively save liquid, cuts off entrance The air duct of pipe and pump case effectively plays water seal effect, centrifugal pump is made to realize self-suction function.

It closes water polo 13 and uses sanitation-grade ball, diameter is less than 6 internal diameter of fast assembling-disassembling hoop component, return pipe on return pipe The internal diameter of 8 big end of Taper Pipe under upper Taper Pipe 5 and return pipe, greater than the internal diameter of 8 small end of Taper Pipe under Taper Pipe 5 on return pipe and return pipe. Volute spring 7, which is located at, closes 13 lower part of water polo, and volute spring big end outer diameter is greater than the small end inner diameter of Taper Pipe 8 under return pipe, Conical Projectile Spring small end inner diameter is less than the diameter for closing water polo.The effect of volute spring is that water polo is closed in support, avoids closing water polo whereabouts, thus unfavorable The liquid reflux under self-priming state.The top that water polo falls in volute spring in self-priming operating condition at present is closed, at this time circulating reflux pipeline It opens, keeps normal reflow, enter centrifugal pump operating condition after completing self-priming, then close that water polo is smooth to be moved to Taper Pipe 5 on return water, closure Water return pipeline makes centrifugal hygienic self priming pump work under pure centrifugation pump condition, prevents backflow leakage, improve efficiency.

Using Taper Pipe under Taper Pipe on return pipe and return pipe in circulating reflux pipeline, it can guarantee that circulating reflux pipeline is closing It is effectively opened and closed under the action of water polo, keeps safety higher, line loss can also be effectively reduced using Taper Pipe, increase fluid flowing Uniformity, avoid the occurrence of slough, eliminate corner or spot as yet untouched by a clean-up campaign, guarantee sanitation performance.

Plane composed by plane composed by circulating backwater pipeline axial line and water inlet pipe road is also common perpendicular at one In straight plane.Circulating reflux pipeline is using fast assembling-disassembling clip group under fast assembling-disassembling hoop component on return pipe and return pipe Part dismantles circulating reflux pipeline quickly, convenient for checking reflux and the sanitary condition in circulating reflux pipeline.Meanwhile Very easily the liquid in centrifugal pump pump chamber is vented by disassembly fast assembling-disassembling hoop component, can be pumped in winter with effective protection Shell.The industry of hygienic requirements high for pharmacy etc. can make pump case that need not individually install lower leakage fluid dram again.

Working principle:

In self-priming operating condition, water polo is closed since gravity is fallen on volute spring, circulating reflux pipeline is opened, but due to Trap is located at extreme lower position, still plays the role of water seal for the gas in water inlet pipe and pump chamber, outlet pipe.It is pumped in centrifugal pump Gas and liquid under the turning effort of intracavitary impeller in water inlet pipe are pumped in impeller and carrying out gas-liquid mixed, gas-liquid mixed Liquid by force feed to pump case runner, separate in pump case and by the vertical water outlet of pump by the portion gas in gas and liquid mixture Pipe is discharged, and the mixed liquor in remaining pump case runner enters water inlet pipe straight pipe by trap since gravity declines, Liquid is constantly recycled between circulating reflux pipeline and pump case like this, and constantly the gas in water inlet pipe is discharged, until The gas on water inlet pipe road is fully drained, and completes the self-priming operating condition of pump.After gas is fully drained, impeller pumps energy to liquid Power enhances, and pressure increases rapidly in pump case runner, and return pipe liquid is pushed since the collective effect flow velocity of pressure and gravity increases It closes on water polo and moves to Taper Pipe closing water return pipeline on return pipe, pump enters centrifugation pump condition.If liquid pumped itself is high Gassiness quantity of fluid, such as CIP liquid, then pump can pump liquid under high air content, work under self-priming operating condition.

The utility model structure is more compact simple, and circulating reflux pipeline is shorter, and the move distance for closing water polo is shorter, closes More rapidly and sensitive with water return pipeline is opened, more efficient, hydraulic loss is smaller, and sanitation performance is more preferable.The utility model knot Structure is ingenious, is easy to production, installation and removal, and fast quick-detach, installation especially may be implemented in maintenance, and maintenance, observation are very square Just.In addition its superior sanitation performance, high efficiency, low noise, height can performance, have high practical value, be worthy to be popularized.

The novel sanitation self priming pump not only maintains the sanitation performance requirement of sanitary centrifugal pump, but also common health Type centrifugal pump has been transformed into the centrifugal hygienic self priming pump with self-suction function, is well positioned to meet current food, dairy products, drink Material, beer, pharmaceutical industry CIP cleaning system needs.It is but also widely used for conveying gas-liquid mixed liquid and under self-priming operating condition Pump sanitation-grade liquid.
